Question:

Will the DeeMaxx DE66AR kit fit my 2020 Montana 3121RL

Hi Kendal,

There unfortunately is a guide available to us to see what bearings and seals fit your trailer's spindle so you'll need to remove one of the hubs and look for their part numbers. If you don't want to trash the grease seal to get to the inner bearing or the part numbers are already worn off then you can also just measure the spindle at points B, C, and D with a caliper # PTW80157.

The DeeMaxx Disc Brake Kit w/ Actuator for Tandem Axle Trailers # DE66AR uses the following bearings and seals:

Inner bearing # 25580 (1.750" ID) - This would be C
Outer bearing # 14125A (1.250" ID) - This would be D
Grease seal # RG06-070 (2.250" ID) - This would be B

If you find your spindle's dimensions differ then let me know and I can look for the correct fit. It would also help to know the axle capacity, which is listed on a sticker on the axle tube, as well as the wheel bolt pattern to ensure that everything will mate up correctly.
